The present invention pertains to a rotatable food serving housing, and more particularly, pertains to a food serving tray such as that used on a patio table with a patio umbrella, where the umbrella positions through the food serving tray. The food serving tray also holds cold ice packs, such as those known as Blue Ice, for cooling of the food serving trays.

2. Description of the Prior Art

Prior art food serving trays have generally not provided for refrigeration of the food product, especially over extended periods of time. This has provided for an unsanitary and unhealthy storage of food which may lead to primary and secondary health considerations.

The present invention overcomes the disadvantages of the prior art by providing a rotatable food serving housing with specific space for frozen, cold ice packs.

SUMMARY OF THE INVENTION

.Iadd.The general purpose of the present .Iaddend.invention is a rotatable food serving housing with hinged covers, removable food trays, and structure for supporting and retaining cold, frozen ice packs, such as those known as "Blue Ice". The food serving trays are removable from the rotatable food serving housing for ease in washing of the food serving trays. The trays engage within the housing and about the frozen, cold ice packs. The food serving housing can also accommodate a patio umbrella, such as for use on a patio table, where the food serving housing is in the center of the table and maintained in position by the umbrella and being inserted through the umbrella support in the rotatable food serving housing.

According to one embodiment of the present invention, there is provided a rotatable base assembly, a base structure affixed to the rotating base assembly including an umbrella support, frozen ice pack supports and food tray supports; two opposing food trays, which engage into the opposing food tray supports; and a corresponding like cover with hinged flaps for engaging about the ice pack supports and the umbrella supports with the base.

The table top revolving food tray or container is 18 inches in diameter. Two easy open/close hinged lids, one lid per side, keep din/insects away from the food inside, and also hold the cool air inside. Two frozen ice packs inside help prevent food spoilage and extend the time in which food can be enjoyed. The container has a large hole in the center that an umbrella pole can slide through (up to 17/8" diameter pole) in order to save space on picnic tables. Separate food trays for easy clean up can be used inside or out. This invention implements especially well on picnic tables.

The revolving tray can be placed in the center of the picnic table with an umbrella pole through the center to save space on the table top. Two ice packs are positioned inside to help preserve freshness of food for longer periods of time. Two large food trays (each divided into 3 separate compartments) allow transportation of different foods to locations which saves trips back and forth. Lids open easily and stay open for easier access to food. Lids also close easily without having to latch covers onto containers. The revolving tray brings all food into easy reach of all persons sitting around most sized tables.

Significant aspects and features of the present invention include a rotatable food serving housing for maintaining food serving trays in position with respect to cold, frozen ice packs in the food serving housing.

Another significant aspect and feature of the present invention is a rotatable food serving housing which accommodates a patio umbrella and rotates about the patio umbrella, which extends through the food serving housing.

A further significant aspect and feature of the present invention is a food serving housing which retains cold, frozen ice packs in position with respect to the food trays and the food serving housing.

Further significant aspects and features include a hole through the center which accepts an umbrella pole up to 17/8" diameter. Two (61/2"×33/4"×11/2" thick) ice packs are used to keep food cool and fresh. The revolving tray allows everyone at the table easy access to all food inside.

MODE OF OPERATION

The 18" diameter . .rotating.!. .Iadd.rotatable .Iaddend.food serving housing 10 includes two easy to open hinged flaps 18 and 20 on the upper housing 16. The hinged flaps help keep cool air in, and insects, dirt and air currents out which cause the food to lose freshness quickly. There are two ice packs 36a-36b which fit inside the ice pack compartments 22 and 24 to keep food cool and fresh longer. Results of testing show that these ice packs will keep the food fresh and enjoyable for 3 to 31/2 hours under adverse conditions, such as 90° F.@85% humidity. Obviously, the food will stay fresh longer under more ideal conditions.

There is a 2" diameter umbrella accommodation tube 44 running through the food serving housing 10 which allows the shaft from any purchased umbrella to pass through. The accommodation tube 44 fits closely about an umbrella mast to seal the interior of the rotatable food serving housing 10 from outside air and also to keep the cooled interior air within the confines of the housings. This saves a large amount of space on the top of a picnic table, which is normally wasted due to the shape of typical food containers and the fact that they must be placed around an umbrella shaft.

There are also two removable food trays 28 and 30 inside which can be filled on site or refilled in a residence, and brought outside in one trip making entertaining or relaxing outside easier. Since all the food is kept in these easily removable trays, clean up after using is readily accomplished. If one or both trays 28 or 30 are left out, there is also room for 6 beverage cans (12 oz.) on each side.

Various modifications can be made to the present invention without departing from the apparent scope hereof.
